I. Essential General-Purpose Tools for Routine Calibration
Basic Measurement Tools: Grade 0 feeler gauges, standard gauge blocks, and high-precision digital vernier calipers are used for displacement reference calibration. These are generally available in the routine maintenance toolkits of injection molding workshops.
Signal Debugging Tools: Digital multimeters and a standard industrial PC with simple host computer software are used to verify output signals and set zero-point and full-scale parameters. No additional dedicated programmer is required.
Auxiliary Operation Tools: Copper fine-tuning set screws and insulating shielding tape are used for fine-tuning displacement positions and fixing wiring. These are common consumables in workshops.
II. Optional Dedicated Auxiliary Tools
For automotive-grade domestic Hall sensors with OTP programmable registers, a general-purpose magnetic sensor programmer can be selected as needed. This is used to read and write internal gain, zero-point offset, and other configuration parameters, replacing traditional external circuit voltage divider fine-tuning and improving mass production calibration efficiency.
This type of programmer is a general-purpose tool, not a customized tool specific to any particular domestic Hall sensor. It is compatible with the vast majority of domestic Hall sensor models, and the cost of a single set is only a few hundred yuan, far lower than the cost of dedicated calibration tools from imported brands.
III. Calibration Instructions for Hot Runner Scenarios
For the domestic hot runner Hall displacement sensor you are currently using, no dedicated tools are required. You can quickly complete the entire calibration process using the standard hot runner displacement sensor calibration tools you prepared earlier, without any additional procurement costs.
This tool configuration is perfectly suited to your needs for building a low-cost hot runner displacement monitoring system. There is no need to invest heavily in dedicated tool purchases; ordinary maintenance engineers can independently complete the calibration operation on-site.
